To all whom it 'may concern.'

Be it known that I, THEODoRE M. FARLEY, a citizen of the United States,residing at Dixon, in the county of Lee and State of Illinois, haveinvented certain new and useful Improvements in Perforating Devices forMusic-Sheets; and I do declare the following to be a full, clean, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the aeconjlpanying drawings, and

to the letters and figures of reference marked thereon, which form apart of this specification. I

My invention has reference to machines for producing music sheets of thekind lin use in automatic musical instruments, and is designed to beused in connection with a piano or other instrument provided with akey-board, so that the music w-hich is being played on suchinstrument'imiy be simultay position for use. f of the perforatingdevices, illustrating the neously reproduced on one or more of the musicsheets.

My device is simple and compact in construction, and can be quicklyapplied to the instrument without injury thereto. The principal part 'ofthe machine can also be instantly detached from the piano, at such timesas it is not desired to reproduce 'the music.

In the drawings: Figure 1 is a. longitudinal mid-section of myinvention, when in Fig. 2 is a detail of one manner of operationthereof. Fig'. 3 is a front view of one of the levers 29. F ig. 4 is afragmentary view, in plan, of the perforating mechanism, with some-of.the parts broken away.

Similar numbers refer to similar parts throughout the several figures.

The device consists primarily of a series of punches, one for each ofthe keys of the instrument, and means for imparting movement to thepunches, upon the corresponding key being operated. As the severalperforat-ing devices and groups of mechanismr which actuate the same areidentical throughout the machine, or are common to all of said devices,the description will be limited to one of the units thereof.

1 represents a bed-plate. supported on legs Q, and mounted on the plate1 is acrossplate 3, having ya' vertical perforation 4. Supported at somedistance, above the crossplate 3 is a cross-pirate 5, in which a punch 6has vertical movement. Immediately shove the cross-plate 3 is across-plate (in a perforation in which 'the lower end i the punch 6 -isnormally held, such perforation. being in line with the opening It.

Integral with the nnch 6 is an. angular ar'm 8, the end of'which passesdownwardly through a perforation in the plate 5, parallel with the punch6, and in rear thereof. The end of the arm 8 is supported by a lever 9,fulcrumed on a rod 10, supported at each end in a bracket 10, secured tothe frame. A contractile coiled spring 11 is secured at one end to theshort end of the lever 9, and at the other end to a rod 11a, alsosupported in the brackets 10u. operates to hold the punch 6 normally inelevatedlposition, as shown in Fig. l.

Pivotally secured to the punch l6, as at a, is a bar 12, having fixed toits upper end an agitator-plate 13, which is provided at its upper endwith an upwardly extending key 14. The key lll is held in a slot 15 in across-bar 16, supported in the machine above the cross-plate 5. Thispermits limited movement of the key l-,t and plate 13 longitudinally ofthe machine.

Mounted on the plate 1, in front ofthe punch mechanism above described,is a pair of supports 1T, (one only being shown) in which is mounted arotary shaft 18, to'which is fixed a transverse block 19, provided withay plurality of striker-blades 20, which pass in close proximity to theplate 13 upon the rotation of said block. Fixed to the end of the shaft1S `is a sheave 21, by means of which rotation may be imparted to saidshaft from' the usual motor, or other means.

' upper end contiguous to the lower face of the Ikey 2B, near theforward end thereof. Fixed to the lon er face of the key-bed 22 is asupport QT. in which is mounted a rod 12, upon which is fulcrumed abell-crank lever 29, the upper end of which is connected with the rearend of the lever by means of a short rod or link 30. The lowerend of thelever 29 is provided with a fork 31, which engages the key 14 of theplate 13. Upon the key 23 being depressed by the operator, the forwardend of lthe lever 25 is forced The latter meenanism' downwardly by thepin 26, actuatin the lever 29 to throw the key 14 towar s the block 19.The upper end of the agitator 13 is thus brought in line with the outeredges of the striker-blades 20, causing such agitator-plate to be forceddownwardly, giving to the punch 6 a corresponding downward movement,until the lower end thereof enters lthe opening in 'the plate 3. Thatcorner of the plate 13 with which the Stricker-blades contact ispreferably rounded, to facilitate the movement of the blades thereon.When the pressure upon the key 23 is relieved the plate 13 is returnedto its former position by means of a coiled spring 32, attached at oneend to the plate 13, and at the other to a vbracket 33, mounted on theframe of the machine. When the plate 13 is returned to its formerposition the punch 6 is likewise returned to itsnormal position by meansof the spring 11, as before mentioned. The vupward movement of the punchis limited by a cross-bar 33a, with which the arm 8 contacts.

One or more paper sheets 34 are passed through the machine, such sheetspassing Iirst over a roller 35, mounted in supports 3G, fixed on theplate 1. Above the roller 35 is a similar roller 37, mounted on a shaft38 which has vertical movement in curved ,slots 39 in the supports 36,such slots being adapted to support said shaft in their upp'er ends whenthe sheets 34 are being rst 1ntroduced into the machine. The sheets passfrom the rollcr'35 over a drum 40, the ends of which serve to keep theed es of the sheets` even, and from such rum said sheets pass betweenthe plates 3 and 7, andI beneath the perforating devices. -They thenpassl over a roller 41 mounted in the supports 17, to which rollermotion may be imarted to cause the movement of the music sheets throughthe machine. Above the roller 41 is a roller 42, mounted on a shaft heldin curved slots 44 in the supports 17,

similarly to the shaft 38. The rollers 37 i and 42 are of sufficientweight to keep the sheets 34 pressed tightly together in their progressthrough the machine. From the rollers 41 the sheets 34 pass over ashoulder 45, above which a knife 46 is supported in a frame 47, andadapted to be forced downlwardly past the shoulder 45', severing thesheets 34 at that point, when the piece is complete'. Nothing is broadlyclaimed herein on the mechanism b means of which the music sheets arecause to pass through the machine, nor on the mechanism by which suchsheets may be cut, and further details ofthe operation thereof are notdeemed nec'- essary. v 4

48 lre resents a stand, or support, in which are hel,r apluralit ofreels 49 from which the sheets 34 are ed into thefmachine.'v A portionof one of the sheets 34 is shown in of this class.

-music sheets are caused to pass through the machine, beneath the.perforating devices. At the same timethe striker-block is continuouslyrotated, andl as the keys ofthe piano are operated the correspondingkeys14 are actuated to bring one or more of the plates 13 into the line ofmovement of the striker-blades, causing a reciprocation of such plates,and a corresponding movement of the punches G, resulting in theperforation of the sheets 34. So long one of the plates 13 is held in aforward position, such plate will be repeatedly actuated by the blades20, in rapid succession, resulting in a correspondmg rapid movement ofthe punch which is controlled by such plate. A simple touch of the keyof the instrument will result in the contact of the plate 13 by one ofthe striker-blades, producing a single perforation in the sheets, but ifsuch key is held down for a greater length of time, the punch 6 willcontinue to operate, and by reason of the movement of the paper sheetsber ath the punch, will produce a perforation of cori responding lengthin such sheets. The movement of the striker-block is timed withreference to the movement of the music sheets so as to produceperforations therein corresponding to the length of the notes played onthe instrument.

It will be seen that in the o eration of my device it will be possibleto ieed the sheets 34 through the machine continuously, instead ofintermittently, as in some machines When the machine is not in use, itcan be readily moved away from the instrument, the device proper beingonly 'detaehably attached to the instrument through the engagement ofthe forks 31 with the keys 14.l 1t is obvious that it can be as readilyreturned to an operative position by rengaging the keys l 14 with theforks. When the sheets have been perforated they can 4be separatelyrolled on spools at the front ofthe machine, ready for use, or otherwisecared for. v

What I claim as my invention, and desire to secure by Letters Patent ofthe United States, is:

1. A device of the class named, comprising a plurality of perforatingdevices, reciprocally mounted in the machine; aplurality of agitatorplates, pivotally attached y to said perforating devices; a constantlrotating cylinder; a plurality of radial b des, carrled by saidcylinder, the outer edges of said blades being in proximity to saidagitator plates; and means for bringing said agitator plates severallyinto the line of movement of said blades, to be actuated thereby,substantially as described. v
